hi both

having had a longer look at 3 on a better monitor, I think that Biscogniauxia nummularia is actually the correct shout

if you carefully cut across a stroma (like taking the skin off a fried egg yolk) and it has jelly-like contents, that means that it's got mature spores; touch that jelly with a clean handkerchief or tissue and if it's noticeably dark you've probably got a member of the Xylariales (which includes Biscogniauxia and Hypoxylon); trouble is that quite often you'll find empty chambers - the fungus doesn't really change in external appearance: this is a good time of year for pyreno's though

cheers
